+ ARCnet "cap mode" packet encapsulation. Used to get the hardware
+ acknowledge back to userspace. After the initial protocol byte every
+ packet is stuffed with an extra 4 byte "cookie" which doesn't
+ actually appear on the network. After transmit the driver will send
+ back a packet with protocol byte 0 containing the status of the
+ transmission:
+ 0=no hardware acknowledge
+ 1=excessive nak
+ 2=transmission accepted by the receiver hardware
+
+ Received packets are also stuffed with the extra 4 bytes but it will
+ be random data.
+
+ Cap only listens to protocol 1-8.
